Oh, and if it weren't enough, mathematicians have a separate name for the damned nabla symbol : "del" instead of "nabla".
TODO why is it called "Del"? Is is because it is an inverted uppercase delta?
Unfortunately, physicists and mathematicians keep using Greek letters in their formulas, so we just have to learn them.
A helpful way to remember is to learn a bit of their history/pronunciation: Section "Historical correspondence between Latin and Greek".
To learn the greek letters if you have a base latin alphabet, you must learn the sound of each letter, and which Latin letters they correspond to.
Symbols that look like Greek letters but are not Greek letters:
Is Ciro Santilli crazy (he is, but for this point specifically), or do many/most Greek letters represent the mouth position used in the pronunciation of the letter?
Can be denoted either by:Our default symbol is going to be:
- the upper case Greek letter delta
- nabla symbol squared
